. Moles of carbon dioxide gas produced by the reaction. When the components of the reaction are mixed, a net amount of moles of carbon dioxide gas are generated. Some of the gas will remain disolved in the water while the rest will escape into the graduated cylinder (moles collected). Calculate the net amount of moles of carbon dioxide gas produced in the reaction (Hint: use stoichiometry.)

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

thats not the answer u need to drop the right one bruh
